What can I do to help this situation? Run with valgrind? Explain howto run the SQLAlchemy test suite? I guess that would help most.

I'm off to bed now, but hopefully this will get you started.

*pull the svn of SQLAlchemy and don't install, but just unzip

My code is attached to this bug: http://www.sqlalchemy.org/trac/ticket/874

put the monetdb.py in the sqlalchemy/lib/sqlalchemy/databases/ directory.

add 'dialect.monetdb', to modules_to_test in sqlalchemy/test/dialect/alltests.py

I have a script that runs the test, here it is:

#!/bin/sh

pushd sqlalchemy PYTHONPATH=./lib:./test; python -tt test/sql/alltests.py --db monetdb --verbose --log-debug=sqlalchemy.engine #PYTHONPATH=./lib:./test; python -t test/orm/alltests.py --db monetdb --verbose --log-debug=sqlalchemy.engine popd

#end script

Uncomment the test/orm/alltests.py to crash the server. Repeatedly I my fresh check out of alchemy it isn't commented. I didn't see crashes. I did have restart problems which are now fixed.

Niels

running the normal test will show that there appears to be a memory leak in the server, as the memory grows by some 10-20 Megs after each run.

thanks much,

Attached is the valgrind output of the ORM crash (took some 15 minutes+ to run on my laptop). I guess you forgot to attach it as the attachment is missing.

Sorry, here it is
